Can some traditional carpenter explain how these joints on the solid vertical stacks work?

How do i make liquid plastics like for..casting models, not just molding. maybe also liquid silicones..how do i acquire them?

I've been engrossed by NHIL's video on cardboard construction. I love the concept of builders making stuff out of light, sturdy and free materials, even the glue is just water and flour. The papercrete specifically caught my eye.

But waterproofing is the big issue. Just painting the structure seems to not work, and NH proposes two solutions: a mixture of shellac and beeswax emulsified in boiling ethanol (house full of fire), or gluesticks and parafin wax heated and spread onto the material. The former has the benefit of being applied at room temp like a wood sealant. The later is much simpler to produce and can be re-applied and patched, but only when heated.

Does anyone else know of something to waterproof this material? I feel like hair-spray or some other substance would be an obvious pick.

Trying to find a ceiling fan with two switches and a remote where you only need one switch or the remote to turn it on. With most, you'd need to turn a switch, then locate the remote and use it. The only way I can think of to do this without having to run another wire is to have a ceiling fan that always has power running to it but is only turned on by a remote, then have three remotes with two mounted to the wall where the switches were. Is there a name for this?
I also thought of a solution where the two switches are replaced with powered push button switches but the power bypasses them into the ceiling fan. The switches use wireless like the remote to turn on the fan.

Any idea how to make correct consistency filling for lever bubbles?

Hello /DIY/, I'm looking to build a higher capacity foundry as my current one is too small for the projects I'm planning, it's going to be powered by a dual fuel Propane/drip oil burner that I'm going to build once the foundry is ready.

the vessel I plan on using is an old 30 gallon water well tank like picrel (mine is an old one that has steel legs) roughly 24 inches wide and 36 tall, I'm going to weld flat plates in the top and bottom domes so the actual inside dimension will be around 24x24.

the hottest I plan on going is around 2300F to melt copper.

My question is what is the most durable lining readily available? it seems that most castable refractory linings are great insulating wise but aren't very durable and need to be relined often, not to mention them costing a shitload of money, I was thinking maybe fire and or refractory bricks as they seem to be very durable, but I have no clue where to source enough of them to line the vessel for a reasonable price.

any input would help, I'm not afraid to spend maybe a couple hundred bucks to build this thing but I'm not going to spend a shitload of money on it.

My neighbor and I share a brick wall that acts as a wall to her bedroom, and a wall to my garden. Recently, she found a leak under her floor that is presumably coming from my plant watering as the sprinkler sprays a part of the wall. I'd like to seal up the wall with something durable and lasting. I have researched two products:

Killz masonry stucko and brick paint

BEHR PREMIUM® ELASTOMERIC MASONRY, STUCCO & BRICK PAINT

The BEHR product says it allows breathability to keep moisture from collecting inside of brick. I imagine this isn't a good idea since this seems to be what is causing a collection of water seeping through to the other side.

The alternative is that I use a product I found called castagra, which allows me to paint a surface with basically liquid plastic. But it will not look pleasing and it is extremely hard to apply.

If either of these paints prevent water from getting to the opposite side of the wall, won't it collect water moisture and pull away from the surface in a very short time?

What do you recommend in this situation? Both of these products are water based, so wouldn't that be a problem when I water/when it rains?

Can I cut aluminum on a table saw?
I would like to remove 1/16" at the red line. It's 8 feet long.

this is not safe is it?

what should be changed?

I'm confident I'm fucked lol. I know nobody and I am incapable of interacting with normal people so forget about getting through word of mouth and buying in person. The assholes who want to sell off their piece of junk are gonna trick me into buying it 100%. So much social mind games going on when it comes to dealing with shopping for heavy equipment, I can't win this. I can't bargain for shit.

What mortar tools do I need to install glass block? I have a bucket and drywall knives and thats about it. Mortar is intimidating since I've never done it before

theres a few of these mbs mountain boards with brakes on ebay for not that much
im thinkin of getting one and converting it into a long range lowish speed cruiser with big efficient erethane wheels and a big top mounted battery
with a belt drive i can get the ratio right for the motors and hills
no blutooth remote just a throttle and some switches from an ebike on the brake handle
what i need help with is the electronics like the batterys motors and ecs
how do i minmax them for maximum range over fairly hilly terrain
i have some money to spend on this project for decent proper electric skateboard parts

I'm going to rip out some of my broken, cracked 3" slab and replace the cast iron sewer under the footing by pushing PVC as far out as I can. Then build back to the main stack. I used to do municipal sewer from the road to the house so I have some idea of what's coming. What should I know before I dig in?

hello I'm not really into flooring but i have to put one in my bedroom
my wives mum died and we moved into their family home, to not pay rent
now we're remaking it
and nostalgic and wants to sleep in her old bedroom from childhood days
the thing is, it's laminate and it fucking sucks it's like a poorfag floor
her entire house is very poorfag her dad built it and he's lower class in Eastern Europe
whatever
I'm used to nicer things
my dad also built our home but it's very very nice and big, but my brother inherited it
so now i want to upgrade this home, what's easy to diy like laminate but higher quality and nicer to look at

I'm considering buying pic related. Never been up on a ladder before and want 28 ft so i have the option to get onto second story if i need to.

Is this overkill? I don't love that its fiberglass and the price is outrageous, but it is pretty light for not being aluminum (57 pounds) and the wide stance of the adjustable outriggers looks way more stable than a regular extension ladder

Has anyone DIYed a HoneyWell turbine before? This one has magnets on the tips of the blade and apparently it's patented off market, so no longer for sell. The design seems simple enough and works at lower speeds.

MB-11 Powder isn't working

Hi /diy/ I bought a small desk drill press from a flea market for 5 bucks, but it's missing the shaft that goes into the drill chuck. Anyone know where I can get a replacement? Looks like it's either 3/8 thread or M10 but it's hard to tell; the former feels kinda loose and I don't have any of the latter to double check on me

Home built in 1985
Dryer vented straight down through floor to crawlspace
Crawlspace had open ventilation up into garage
Garage became magnet for mice who can easily get in the crawlspace and my walls through the garage
Sealed crawlspace now need to vent the dryer somewhere
Shortest route is right though the wall into the garage
Been doing it for a few years now, figured out how to make moisture and heat less with a lint catch and bucket. But I only have one window in the garage and it's on the other side from the vent.

Does it make sense to put in dryer pipes up wall and along ceiling to vent to the window across the room? That way no hot air is pumped into the garage at all? I think that's the easy solution instead of drilling through exterior wall or attempting to vent through crawlspace to pipe outside.

I hate to slide a thread to ask this question but does anyone know how much shit you will get in if you just go ahead and build your own house in australia? not yet planning anything, but i fucking hate the government and ill be fucked if im gonna ask permission to live on the land i paid good money to purchase. there are like a million brick and mortar cottages in the country that the settlers erected without permission, why shouldnt i also just go ahead and do that?

Is it possible to rebuild an engine without taking it out of the car? I need to do a ring job, and to remove the engine, it has to come out the bottom. I don't have a lift or know anyone who does.

I am aware that it would be impossible to replace the crankshaft bearings, but it should be relatively easy to leave the block in place and push out the pistons and reinsert them with new rings and new con bearings.

How did they designed sheets?? How did they calculated where holes should be to be sinchronized? How or what CAD they use to desing them sheets (computer days)?
Did they just make skeleton and put sheets and cuted excess out then just drilled? Like paper models? Or what? Really dont know.

Hey /diy/, I was looking into electroplating for a retarded autistic project I want to undertake, and my research so far is showing that doing actual brass electroplating would be sorta untenable for me, but then I ran into this sort of brass coating thing.

Basically you heat the steel up fairly high (I think about 1,100 F, 600ish C) and then use a brass wire brush to on the steel, gradually layering on more and more brass as you go.

Has anyone ever tried this? How well did it work for you? Do you think it would work well on small items like pocket watches or small features like engraving very well?

Working in my new space. Just build this wall next to staircase to create two smaller rooms from a big one. Left some space to install some noise reduction panels. Any idea how i fill up this space beneath the staircase with storage? I'm not a creative type

What construction jobs are unironically literally AI-proof? I'm realizing that once they can combine AI with advanced robots we may actually be fucked. Probably still a while away but it could happen in our lifetime.

I think I posted about this a few years back. I created a fountain that spills into my wife’s pond. I used a “lightweight” concrete planter ( fiberglass and concrete ) that I got for cheap. I crafted a spillway out of copper. It worked really well - it dropped the temperature of the water in summer, and the plants helped filter the water.

However the reeds we put in expanded like crazy, and roots plus water pressure ended up cracking it open. This is the first pic on top.

Next two pics are the new one I’m working on. This time I cut a spillway off of a scrap fountain. Supporting insides with plexiglass, fiberglass and epoxy.

What I could use some help with is the cosmetics. I’m ok with some cracks - I filled them with epoxy, and I’m ok with a “weathered look”, but I have one area that is more a hole. I would like to match the color and texture of the existing concrete. If I just smear concrete over areas, will it create a similar gray? I feel like it won’t. Too thin a layer and it’ll just peel or crack off.

Or maybe I can create a hole in an area, and basically pack it if with concrete from the back.

Open to any ideas!

Hey guys, if the valve is way too tight and I cannot unscrew it and there is no space for spanner, what do I do?

My toilet was like this one but worse. I was doing this to install a bidet.

I like this chair, despite it being really ugly. Also, all of the faux leather peeling off and getting everywhere. I want to cover it in duct tape to keep the faux leather from getting everywhere, as I think the powdery stuff is getting in my cat's water bowl and I may be inadvertently eating some of it, too. I'm not gonna die of turbo cancer, right?

I've never done DIY anything before, so I want someone with experience to tell me if I'm missing an easier or better solution. What would you do in this situation?

"Soft-touch" referring to that rubberized coating that was all over electronics in the 90s, and tends to degrade into a sticky mess over time.

Is there any chemical or product that will strip this stuff without damaging anything underneath? I've had issues with rubbing alcohol removing printing and discoloring/staining plastic

What would be a cool way to make these 2x10s look nicer other than just boxing them in and covering up the bolts? I'm already planning on wrapping the 6x6 support with copper downspouts I've got laying around. I'm not going for an industrial look I just like copper.

Any ideas on how one could make an endoscope out of off-the-shelf stuff that would fit down a 3.5-4mm diameter hole? I want to inspect the pistons in my diesel engine through the glow plug holes, but normal automotive bore scopes are too big to fit and medical endoscopes go for at least a grand. I know the picture quality wouldn't be great, but couldn't I get some fibre optic cable and glue a microscope or doorbell camera to the end of one, a light source to the end of the other, and jam them down the hole?

My mains shutoff valve is leaking and needs to be replaced. I am handy enough to solder in a new one but I'm not sure what to do with the bonding jumper, which would need to be moved in order to get access.
Website told me not to move it, but to put a new one on elsewhere and then disconnect the old one, but I don't feel up to that and don't have the required stuff. Is it safe to just disconnect it and move it further up the pipe, if I do it quickly? What about if I shut the power off at the main breaker first?
Is this a good time to actually call in a pro instead?

When I first start my truck the volt reader only reads about 10 volts and the battery warning light is on
But then I hammer the throttle and it goes to the proper 14-15 volts and remains proper for the whole drive

I am curious to know how long it will last until it totally dies out and doesnt charge it enough to run properly
So far its been doing this for 1 week and today it seemed a little worse (i had to hammer the throttle a lottle longer to get it to engage and charge properly)
So tell me about how long you ran a finicky alternator for!! The battery is 9 years old too! So i will probabaly change that too when i do the alternator!

Why, seriously, do we put up with ineptitude at this scale? These things perish within 5 years MAX and literally no-one seems to replace them proactively as required. They fail without warning and leak into everything below, in literally the rainiest, wettest, clungiest, dampest country with the biggest mould problem on the globe as a direct result of insufficient weatherproofing. It's MADNESS how they still contruct flat roofs over something pitched. It's just laziness. I've had to gut out so many of these fuckers and corrugate over new carcassing timber because everything underneath was sodden and fucked

I got a cut on my finger. Deep, clean and bleeds a ton but no real damage. Now the problem is I need to grab stuff, and I don't wanna bleed all over stuff when the cut reopens. Bandaid won't help, bandage won't stop bleeding from there - it will have to be so thick as to to make grabbing awkward, and so I was thinking about letting it heal for a day and then putting superglue on top of it so I can work. Thoughts?
